Carlos Quentin will be shut down for the remainder of the 2013 season with a strained right knee.

He will undergo surgery to repair his injured knee, though that date has yet to be determined. With the Padres out of playoff contention, there is no reason to rush him back and risk further injury. The perpetually injured Quentin finishes the season hitting .275/.363/.493 with 13 homers and 44 RBI in just 276 at-bats.

Padres manager Bud Black said that Carlos Quentin (knee) has shown "marked improvement" over the last two days while running on a treadmill.

Due to the improvement with Quentin's right knee, the Padres have put off making a decision on his status for the rest of the season. He'll need to run on the field before it's decided whether he'll make it back sometime next month, though when the test run will take place hasn't been determined yet.

Carlos Quentin will test his injured knee on Saturday to determine the next course of action.

Padres manager Bud Black estimated Monday that Carlos Quentin (knee) has a 50/50 shot to return this season.

"I wish I could be more confident than that, but I think the next week, we'll have a better handle on it," the manager said. Quentin will rest his nagging right knee for another week before ramping up activities. If he still has soreness at that point, it sounds like the Padres might decide to go ahead and shut him down. Another operation on the knee over the winter seems likely. Quentin has been limited to 82 games this season after playing just 86 last year.

Carlos Quentin (knee) will rest his knee for the next 10 days before the Padres' organization allows him to ramp up activities again.

And that's if his balky knee will even allow Quentin to do so. The veteran slugger was placed on the disabled list on August 10 with chronic soreness in his right knee, and could need another operation before all is said and done. While he's able to hit without any issues, he's not able to run or play the field defensively without significant pain.

Padres placed OF Carlos Quentin on the 15-day disabled list, retroactive to July 30, with right knee soreness.
